How big a deal is the surprise primary defeat of Representative Eric Cantor, the House majority leader? Very. Movement conservatism, which dominated American politics from the election of Ronald Reagan to the election of Barack Obama — and which many pundits thought could make a comeback this year — is unraveling before our eyes.

I don’t mean that conservatism in general is dying. But what I and others mean by “movement conservatism,” a term I think I learned from the historian Rick Perlstein, is something more specific: an interlocking set of institutions and alliances that won elections by stoking cultural and racial anxiety but used these victories mainly to push an elitist economic agenda, meanwhile providing a support network for political and ideological loyalists.
